I'd be fine with most of your changes except for changing stuns to channeled. That would seriously screw over all ranged classes. I also don't support roots/snares being on or affected by resolve. The only way anyone gets chain rooted is when there is multiple people coordinating.
ok. but one person can stun 3 times (sin, op, just about anyone with grenades). then, once you're full resolve, here, have a root. luls
good point about ranged and stuns though. really can only do that to melee, and even then, it might make healers too hard to bring down.
